Scrubbers equipped with Hydralert™ technology have a sensor on the battery pack and an audio alarm
which monitors and communicates low battery water conditions.
1. When batteries are fully charged and the key is turned on, Hydralert™ will check the water level
•If the audio alarm is not activated, there is sufficient water in the batteries
•An audio alarm means Hydralert™ senses a low battery water level.
NOTE
: Failure to clean the Hydralert™ light pipe will limit Hydralert™’s ability to read the water level
and will reduce battery life.
2. Turn the key off and the fill the batteries with distilled water. (See WET, LEAD ACID BATTERY
MAINTENANCE)
NOTE
: Battery packs equipped with Hydralert™ may take more than ½ gallon of water after the
Hydralert™ audio alarm has been activated.
3. After completing the watering procedure, cycle the key to verify the audio alarm is not activated
